Protection of the environment
General notes
H
Environmental note
Daimler's declared policy is one of compre-
hensive environmental protection.
The objectives are for the natural resources
which form the basis of our existence on this
planet to be used sparingly and in amanner
which takes the requirements of both nature
and humanity into account.
You too can help to protect the environment
by operating your vehicle in an environmen-
tally-responsible manner.
Fuel consumption and the rate of engine,
transmission, brake and tyre wear depend on
the following factors:
R operating condition sofyour vehicle
R your personal driving style
You can influence both factors. You should
bear the following in mind:
Operating conditions:
R avoid short trips as these increase fuel con-
sumption.
R make sure that the tyre pressures are
always correct.
R do not carry any unnecessary weight.
R keep an eye on the vehicle's fuel consump-
tion.
R remove roof racks once you no longer need
them.
R ar egularly serviced vehicle will contribute
to environmental protection. You should
therefore adhere to the service intervals.
R always have service work carried out at a
qualified specialist workshop.
Personal driving style:
R do not depress the accelerator pedal when
startingt he engine.
R do not warm up the engine with the vehicle
stationary.
R drive carefully and maintain asafe distance
from the vehicle in front. R
avoid frequent, sudden acceleration.
R change gear in good time and use each gear
only up to Ôof its maximum engine speed.
R switch off the engine in stationary traffic. Returning an end-of-life vehicle
Mercedes-Benz will take back your
Mercedes-Benz to dispose of it in an environ-
mentally responsible manner, in accordance
the European Union (EU) End of Life Vehicles
Directive.
The End of Life Vehicles Directive applies to
vehicles with agross vehicle weight of up to
3.5 t, in accordance with national regulations.
For several years, Mercedes-Benz has been
meeting all the legal requirements for a
design which allowsf or recycling and re-use.
There is anetwork of return points and dis-
assembly plants which can recycle your vehi-
cle in an environmentally-responsible man-
ner. The methods employed in vehicle and
parts recycling are constantly being devel-
oped and improved. This means that your
Mercedes-Benz will also continue to meet
even the increased recycling quotas in the
future in good time. You can obtain further
information from your national Mercedes-
Benz homepage or your national hotline num-
ber. Product information

WARNING
All work on the vehicle and, in particular, work
relevant to safety or on safety-related sys-
tems must be carried out at aqualified spe-
cialist workshop. G
WARNING
Some safety systems only function when the
engine is running. You should therefor enever
switch off the engine when driving. Otherwise,
the safety systems of your vehicle may not
function correctly and as aresult will no lon-
ger protect you and other persons as inten-
ded. In addition, there is arisk that you may
lose control of your vehicle and thus cause an
accident. G
WARNING
Work carried out incorrectly, or alterations
made to the vehicle, e.g. re-routing of cables
under coverings, could cause the safety sys-
tems of your vehicle to stop working properly.
The safety systems would thus no longer pro-
tect you and other persons as intended. In
addition, there is arisk that you may lose con-
trol of your vehicle and thus cause an acci-
dent.
All work and alterations to the vehicle, e.g.
installations or modifications ,should there- 22

fore be carrie
dout at aqualifie dspecialist
workshop. G
WARNING
If work on electronic equipmen tand its soft-
ware is carried out incorrectly, this equipment
could stop working .The electronic systems
are networked via interfaces. Tampering with
these electronic systems could cause mal-
functions in systems which have not been
modified. Malfunctions such as these can
seriously jeopardise the vehicle's operating
safety and therefore your own safety.
You should therefore have all work and mod-
ifications to electronic components carried
out at aqualified specialist workshop. Declarations of conformity

To ensure that the restraint systems can
deliver their full potential protection, make
sure that:
R
the seat and head restraint are adjusted
properly (Y page 96).
R the seat belt has been fastened properly
(Y page 48).
R the airbags can inflate unrestricted if
deployed (Y page 42).
R the steerin gwheel is adjusted properly
(Y page 102).
R the restraint systems have not been modi-
fied.
An airbag increases the protection of vehicle
occupant swearing aseat belt. However, air-
bags are only an additional restraint system
which complements, but does not replace,
the seat belt. All vehicle occupant smust wear
their seat belt correctly at all times, even if
the vehicle is equipped with airbags. The air-
bags are not deployed in all types of acci-
dents .For example, if the protective capacity
of correctly fastened seat belts is not
increased by deploying the airbags, the air-
bags will not deploy.
Airbag deployment only provides increased
protection if the seat belt is worn correctly.
First,t he seat belt helps to keep the vehicle
occupant in the best position in relation to the
airbag. Second, in ahead-on collision, for
example, the seat belt prevent sthe vehicle
occupant from being propelled towards the
point of impact. SRS (Supplemental Restraint System)
Introduction SRS consist
sof:
R the 6 SRS warning lamp
R airbags
R the airbag control unit with crash sensors
R belt tensioners
R belt force limiters SRS reduces the risk of occupant
scoming
into contact with the vehicle's interior in the
event of an accident .Itcan also reduce the
forces to which occupant sare subjected dur-
ing an accident.

WARNING
If SRS is malfunctioning, individuals ystems
may be triggere dunintentionally or might not
be triggere dinthe event of an accident with
ah igh rate of vehicl edeceleration.
Am alfunction has occurred if:
R the 6 SRS warning lamp does not light
up when the ignitio nisswitched on.
R the engine is running and the 6SRS
warning lamp does not go out after afew
seconds.
R the engine is running and the 6SRS
warning lamp lights up again.
In this case, have SRS checked immediately
at aq ualified specialist workshop.
SRS functionsa re checked regularly when
you switch on the ignition and when the
engine is running. Therefore, malfunctions
can be detected in good time.
The 6 SRS warning lamp in the instrument
cluster lights up when the ignition is switched
on. It goes out no later than afew seconds
after the engine is started.
Triggering of belt tensioners, belt force
limiters and airbags During the first stage of
acollision, the airbag
control unit evaluates important physical
data relating to vehicle deceleration or accel-
eration, such as:
R duration
R direction
R magnitude
Based on the evaluation of this data, the air-
bag control unit pre-emptively triggers the
belt tensioners in the first stage. Occupant safety
